(01. "inssst)Thislnvention relatesto railway car constructions and more particularlytoithe construction of acar endwall and transverse bulkhead supportingbeam. r

One of the objects of the invention is topmvide a railway car end wallformed-by a corrugated sheet which is reinforced throughout its width.

Another object of the invention is: to provide a corrugated end Wall fora railway car which is reinforced by channel members which 'also formattaching means forfcoimecting an inner insulating wall to the end wall.

A-further object-of the invention is to pr vid means for securelyanchoring a transverse'beam' which "supports a bulkhead in arefrigerator or like car.

The above and other objects and; advantages will be more "readilyapparent from the following description when read in" connectionwith thefr accompanying drawing; in which- Figure :1 is a partial longitudinalsection" thru a railway car embodying "the invention;

Figure 2 is a perspective View withparts broken away-end in section ofone lot the reinforcing usualbottom l= 0- snpported on longitudinalbeams or the like. The end wall of the car is formed by one or morevconnected corrugated sheets ll arranged with the corrugations extendinghorizontallyand connected by a bracket l2 to the bottom It. The car iscompleted byvthe usual tops and sides not shown; which may be ofstandard construction.

According to the present invention the cormgat'ed end wall H isreinforced by elongated chamel shaped reinforcingstrips 13- mounted onthe inner side of the end Wall with the flanges of the channelsextending int'o and secured as by welding *or the like; to the bottomsof the corrugations. The webs of the. channels. are straight and lie inthe plane of the tops hi the corrugations.

In the usual car construction, the connections are of maximum depththroughout the central portion of the car and taper to flat edges at thesides of the car. In order that the reinforcing stilt a rop rl zi i l qwe i i we. t corrugations throughout their length, the flanges of thestrips ar e' tapered adjacent the ends as indicatedat H in Figure 2 tofollow the taperin depth of i o iiee a ;n-v,. h os,- w m e tri reinforcethe end sheets'substantlaliy from side to side. of the-car. v Z I g g 70n theinteriortofthe end wall an inner insulating wall is providediormed by outer sheathing 15 and inner sheathing; l-d between'whichinsulating material l1- isusupperteds Thezirrner wall is connectedto thecarend by-belts or'zlike elongated fastenings 11,8 extending through theinner wall H with their heads secured; in keyhole slots IS in the websof the reinforcing strips.

Theouter ends of flanges of beam sweeter-n angular, and rest on the innerface of the car position.

end. A series of web plates 34' welded in place in the beam as shown inFigure 5, serve to give added rigidity to the beam.

Adjacent to the end beam 34 is a face plate 40 which is angular in shapeand which serves as a backing for the floor pan and an added support forthe floor grate support 36. Bolts 35 connect face plate 40 and floorgrate supports 36 to the end beam 34. The beams 38 support a floor grate31 as shown.

The car shown is a refrigerator car which carries a bulkhead 38 fordividing the car into an ice-compartment adjacent one end and a centrallading compartment. The bulkhead is preferably movable in the car asmore particularly described and claimed in my Patent No. 2,331,197. Whenin its extended position as shown, the bulkhead is supported in socketmembers 39 carried by the inner ends of the beamsz36. Similar socketmembers 4| are provided adjacent the end of the car to su port thebulkhead when it is in its retracted The beams'36 are supported'abovethe bottom plate 10 by a transverse beam 50 spaced from the end of carand underlying the bulkhead 38. A floor pan 43 extends from thetransverse beam to theend of car and has flanged sides and ends turnedup to provide a receptacle to catch water coming from the icecompartment above. A floor 44 extends under the lading compartment ofcar 'between the transverse beams. A wood beam 42 "is fitted-beneath-the projecting top of transverse beam to' form a dam between the spaceunder the ice compartment and the space under the lading compartment.

In order to secure the beams 36 to the transverse beam '50supportingmembe'rs 45 are providedconnecting to the inner ends of beams36 under the bulkhead when in its extended position. 1 Thesupporting'members 45 are so formed as to permit air circulationlongitudinally of the car therethru. The construction of the transversebeam 50 for securely fastening supporting members 45 to the bottom plateI0 is shown in Figure 4.

It'consists of a metal strip having a central body portion 46 with oneend turned under to form a channel shaped section as indicated at 41.

Registering keyhole openings 48 are provided in "the central portion 48and the turned under end 41 of the beam to secure fastening bolts 49which 'connect'the supporting member 45 to the beam.

stiffening plates 41' are welded in between the central portion 46 andthe free end of flange 4'1 'adiacent to the keyhole slots to preventbending of flange when bolts 49 are tightened. The beam has an angularskirt portion 5| at one side which has secured thereto gusset members52. The gusset members as shown, are channel shaped in section withangularly cut flanges, the upper portion of which may be Welded to theskirt 5| and to the webs of which are bolted the dam beam 42 by means ofthe bolts 54. Gusset 53 may be placed on dam beam 42 on side oppositefrom gusset 52. Gussets 52 and 53 are securely fastened to the bottomplate IU of car. With this construction the beam and the parts supportedthereby are fixedly anchored in the car and will not shift under strainsto which the car may be subjected.

What is claimed is:

1. A railway car construction comprising an elongated supporting basefor the car, a corrugated sheet metal end wall, a bulkhead in the carspaced from the end wall, a transverse beam on the base under thebulkhead, a series of longitudinally extending beamsfor supporting afloor rack secured at one end tothe sheet metal end wall, and means forconnecting the other ends of the longitudinal beams to the transversebeam and for supporting the bulkhead thereon including an angular metalplate having gussets secured thereto and to the supporting base of thecar.

2.

3. A railway car construction comprising an elongated supporting basefor the car, a sheet metal 'end wall connected to the base, a floor inthe car above the base, a bulkhead in the car spaced from the end wall,a transverse beam connected to the base under the bulkhead; areinforcing beam connected to the inner surface of the end wall in linewith the floor, the floor being connected to both the transverse beamand the reinforcing beam, and means connecting the bulkhead to the floorand the transverse beam.

4. A railway car construction comprising an elongated supporting basefor the car, a horizontally corrugated sheet metal end wall secured tothe base, a floor in the car above the base, a channel shapedreinforcing beam secured to the inner surface of the end wall in linewith and connected to the floor, a transverse beam secured to the baseand to the floor spaced from the end wall, a bulkhead in the caroverlying the transverse beam, and means connecting the bulkhead to thefloor and the transverse beam.
